進口制冷劑電磁閥 美國RETZ瑞茨

品牌：retz瑞茨/我們一直致力于流體控制領域的持續創新，始于2005……進口制冷電磁閥適用于氟利昂、制冷劑、水、冷凍液、氣為工作介質，實現通斷自動化，具有啟閥迅速，性能穩定，使用方便，節能好，壽命長等優點retz refrigeration solenoid valve is suitable for working media such as freon, refrigerant, water, refrigerant, and gas, achieving automatic on-off. it has the advantages of quick valve opening, stable performance, convenient use, good energy conservation, and long service life
進口制冷劑電磁閥控制原理--
常閉式：normally closed
當線圈通電時，先導閥芯吸合，先導孔打開，閥上腔卸壓，活塞靠下腔介質壓力推動，電磁閥打開。當線圈斷電時，先導閥芯靠彈簧復位，先導孔關閉，閥上腔由活塞節流孔增壓和復位彈簧的推力，電磁閥關閉when the coil is energized, the pilot valve core is closed, the pilot hole opens, the upper chamber of the valve is depressurized, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve opens. when the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is closed, and the valve upper chamber is pressurized by the piston orifice and the thrust of the reset spring, and the solenoid valve is closed
